Iroha wanders into Kosho Ward in Kamihama City. On the street, she is offered some Lucky Owl Water, which is said to bring good fortune, and without much thought, takes a sip. Another Magical Girl named Felicia also happens to drink the Lucky Owl Water. Wherever they go together they have extremely good luck. They have such good luck, in fact, that Iroha finds it a little strange. Felicia makes a living as a mercenary, and offers her services to Iroha to help find Ui, but…
Once the good luck counter hits zero,
bad things may happen, right?
Podría pasar algo terrible
si se quedan sin buena suerte.
Podría pasar algo terrible
si os quedáis sin buena suerte.
Quand votre bonheur sera à zéro,
quelque chose de terrible va arriver ?
Una volta esauriti i colpi di fortuna, 
dovrebbe accadere qualcosa di brutto, giusto?
Quando o contador de boa sorte chegar a zero,
coisas ruins vão acontecer, certo?
